IMPROVEMENT IN CASES ,FOR SUPPORTING cans.

Speciiication forming part o f vIIetters katent No. 211,

061.1, dated December .17, ,18.78; `applef2t-11.@led

Be it known that we, nGEORGE H. PERxINs and GEORGE BROWN, both ofthe city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in `Supporting Boiling-0ases for Cans, of which the following is a full, clear, and `precise description, reference being had to the accompanying drawings, which form part hereof, and of which- Figure l is a view in perspective oi our improvement as suspended from the handlingcrane and in readiness for immersion; Figs. 2 and 3, central longitudinal sections of two forms of construction ofthe case, exhibiting the cans in place, and Figs. 4 and 5 sectional details of two forms of opening in the lid, as hereinafter explained, Figs. 6 and 7, sectional details of two forms of extensions of the lidopenings, as hereinafter explained.

Similar letters of reference indicate corresponding parts.

Our invention is designed to be employed in connection with processes of preserving meats, duo., and hermetically sealing the same incans; and consists, substantially, in the supporting boiling-case herein described and claimed, in which cans containing'meat in the uncooked or `partially -preserved state are placed, and, when properly secured an d closed up, immersed in water and boiled to the de-` sired degree.

Heretoi'ore, after the meat or other substance to be preserved has been placed in the can and the cap or cover sealed on, the can s with its inclosed contents has been placed in boiling water and the whole boiled for a time, then removed from "the boiling'water and the can punctured to allow of the escape of gases, resealed, and boiled again. Frequently the pressure generated within the can has been suiiicient to burst it outright or spread the seams, to the damage of the contents. To obviate this is theobject of our invention.

Our supportingcase consists of a series of cells or receptacles of the exact size of the cans to be subjected to the boiling process, arranged in any given series, and adapted to receive and support upon every side each can during `the boiling, sopas to` guard againstiand prevent burstingoi" thecaris. i

In the drawingsacase constructed `to ,hold truncated-conecans is represented. uIt .,will, however, be understood that the .cells ,maybe formed to hold square, rectangular,circular, or other shaped cans. y

The Gase A is preferably mail@ of iilfovmas or wrought, and isA constructed either as Xaseries of cells, B B, of the desired size,'luk11iited together, or else as a box divided oi by partitions in such manner as to produce the cells.

In Fig. 3 is represented the iirst construction, in which Vit will be observed that the water or boiling medium has access to the space between the cans as well as above and below. In Fig. 2 is represented the second construction.

The object being to support the can against Y the bulging pressure, it is requisite that the sides and bottom'of the cells should be correspondent with those of the can, of Whatever shape the latter may be, and lit closely against them.

(l is the lid, removably hinged to the case for convenience in handling, the same consist= ing of a metal top adapted to` bear upon or protect portions of the covers of each can, leaving, however, a space for the puncturing and resealing and, when desired, for filling of the can.

The lid G is conveniently constructed as a Hat cover, sufficient in its external dimensions to completely cover all the cells, and having a series of openings, C', made to correspond with the cells, each opening being best made of an outline correspondent with the cap of the canhead, and of size sufficient either just to overlap the edges of the cap, and so bearupon it, or of larger size, to permit the sealing on of the ca p after the iilling of the can within the cell, if desired. l

The sides of the openings may beso constructed or arranged as to extend above the openings in the can and constitute chambers or vessels or extensions C, so to speak, of the can, to the end that in the cooking process in the can ebullition or swelling of the contents can take place into the extensions With- MEAT (3G- 7 (Mauren.) or sin@` out loss of material by overiiow, the extensions being so formed as to facilitate the easy iiow'of the boiling, material back into the can.

It is obvious that-the lid must iit closely down upon the can, so that there shall be no escape of material between the lid and cancover.

In Fig. 6 is represented a convenient method E E, chains, or the like, by which the case can behandled with a crane. F F are drainholes, provided to permit the escape of water.

The case containing the filled cans, and with the cover locked on, is readily immersed in the boiling medium and removed therefrom, effectuating a most material improvement over the old processes.

The cover being in one piece, as it is best made, effects a material saving in the time necessarily consumed in the putting in and taking out of the cans.

Having thus described our invention, We claim and desire to secure by Letters Patent of the United States- 1. The supporting boiling-case herein described, consisting of a series of cells constructed and operating as described and of a cover provided With openings coincident with the cells, substantially as and for the purposes set fort 2. In combination with a supporting boilingcase for cans consisting of a series of cells constructed and operating to support the cans upon sides and bottom, a cover adapted, When applied, to bear upon or protect the tops of the cans, and provided with a series of openings coincident With the openings in the tops of the cans, substantially as described.

In testimony whereof We have hereunto set our hands this 24th day of J une, 1878.
